Usually for an adventure session this will differ greatly. The session may take a day of travel to reach the location, it may involve a stay over, depending on location above will affect the time. Lets take two examples.
Example One: The Isle of Skye. (3 Days + 2 days of editing = A 5 day shoot)
Friday – An 8-10 hour drive the day before the shoot, stay at accommodation or camping.
Saturday – Day of the session, plenty of adventure and awesome photographs.
Sunday – Drive home, another 8-10 hours.
Example Two: The Lake District. (1 Day + 2 Days of editing = A 3 day shoot)
Friday – Set off early morning to location, a 2-3 hour drive. Hike the fells to desired location and start the session, multiple locations can be used if discussed prior. Drive back the same day on the evening.
